Subject: [PATCH] Cover your kid's remaining eye and lock up the pets for the
 great old ones have been disturbed: rework the linker script and then enable
 RELRO support on all but mips64 (something something padding) and m88k
 (untested). This extends the RO coverage from just .got and .cdtors to also
 include .openbsd.randomdata, .jcr, .dynamic, and .data.rel.ro., and moves
 more segments from the text section to the rodata section.  Depends on the
 previous csu and ld.so work; reinstall those *before* rebuilding ld, or just
 get a snapshot.
